7-5
LOS at Net, Pt n An LOS (Loss Of Signal)
condition has been detected
on the network interface. No
signal is being received on
Port
n, possibly due to a local
network problem.
1. Verify that the network cable
is securely attached at both
ends.
2. Verify proper NTU and LTU
configuration.
3. Contact network provider to
troubleshoot the line.
Mismatch Rate, Pt n The LTU, set to a fixed DSL
rate, is attempting to operate
at a rate the NTU is not
capable of. Set the LTU to a compatible rate
or replace the NTU.
Net Margin Threshold,
Pt
n
The signal-to-noise margin
has dropped below the
configured threshold. 1. Check the Network
Performance Statistics
screen for possible line
impairments.
2. Set the unit to run at a lower
DSL line rate.
3. Reconfigure the margin
threshold (if appropriate).
4. Contact network provider to
troubleshoot the line.
NTU/LTU Mismatch,
Pt
n
The NTU is not compatible
with the LTU. Contact network provider.
NTU TS16 Not
Supported The LTU is configured for
TS16 signaling and the NTU
is not configured to support
TS16 signaling. 1. Verify endpoint is a G.703
product. EIA-530-A products
do not support signaling.
2. Replace endpoint or
reconfigure TS16 to data.
OOF at Net, P n An Out Of Frame (OOF)
condition has been detected.
An OOF condition is declared
when 2 out of 4 frame
synchronization bits are in
error. 1. Check the Transmit Clock on
the unit and attached
equipment.
2. Set the unit to run at a lower
DSL line rate.
3. Contact network provider.
Payload Rate
Mismatch Pt
n
The endpoint device is an
EIA-530-A model that does
not support the configured
EIA-530-A payload rate. Reconfigure the EIA-530
Payload Rate configuration
option to an acceptable rate.
See
Network Interface Options
Menu in Appendix A,
Configuration Options for
acceptable rates.
